I'm bringing back the line up of transmitter kit-sets once sold by nrgkits in the UK, they went out of business back in 2011, I wont go into details its a long story and there's plenty of info on the internet.

Website is www.nrgkits.co.nz

I have the main pll transmitter board back in production and have incorporated a few changes regarding the frequency setting output power.  The rest of the nrg line up of kits will follow including the stereo coder and limiter/compressor boards.

There are a couple other websites around pertaining to be nrgkits with no advertised items for sale, however I have had proper authorisation from the previous owner of the business in the UK and have acquired a lot of their left over stock.

 (5) External controls that enable transmitter power to be increased above the maximum radiated power are not permitted.


Um, according to RSM your transmitters are illegal as they can have their power increased above 1 watt.

I have an NRG 1 watt it does not have external controls and I have an RSM certificate of compliance for mine

The pcb is supposed to be mounted in a metal case, hence the controls are not external.  The transmitters are not illegal, RSM are only concerned with EIRP.  4 Watts transmitter output may be required if you have a long run of coax to your antenna.  The power controller is variable so you can calculate and set the power accordingly so you have 1watt eirp, given the length of coax, type of coax, and antenna gain etc...

All of the above points went through my mind looking at your website but I was a bit sceptical as you don't mention them on your site. I suggest you mention on the website compliance with low power fm laws and that pcbs should be mounted in a case to be compliant.

you should also mention that if music is going to be played that a relevant APRA and/or PPNZ license will be needed.
